Referring to FIG. 1, FIG. 2, and FIG. 3, a tray device 100 for carrying various types of hardware includes a tray body 10, a bracket 20, and a handle assembly 30. The bracket 20 and the handle assembly 30 are mounted on the tray body 10.

In one embodiment, the tray body 10 includes four connecting plates 11. The four connecting plates 11 include a first connecting plate 111, a second connecting plate 112, a third connecting plate 113, and a fourth connecting plate 114. The first connecting plate 111 and the third connecting plate 113 are oppositely arranged, and the second connecting plate 112 and the fourth connecting plate 114 are oppositely arranged. Two end portions of the first connecting plate 111 are provided with protrusions 1111 for resisting hardware to be installed. The second connecting plate 112 defines a snap groove 1121 and a fixing groove 1122. The handle assembly 30 and the second connecting plate 112 are fixed together through the fixing groove 1122. A first slot 1131 is defined penetrating the third connecting plate 113 for receiving a light guide rod 13, and one end of the light guide rod 13 is inserted into the second connecting plate 112. In one embodiment, the light guide rod 13 is made of polycarbonate.

The bracket 20 includes a bottom plate 21 and two side plates 22 respectively connected to two sides of the bottom plate 21, and the two side plates 22 are respectively connected to the first connecting plate 111 and the third connecting plate 113 of the tray body 10. In one embodiment, each of the two side plates 22 is provided with a buckle (not shown), which is buckled on the corresponding first connecting plate 111 and the third connecting plate 113. The bottom plate 21 and the two side plates 22 define a plurality of first through holes 23 for fixing the hardware to be installed on the bracket 20 by a fixing member (not shown). In one embodiment, the number of the first through holes 23 is four. Two of the four first through holes 23 are defined in the bottom plate 21, and the remaining two of the four first through holes 23 are defined in the two side plates 22. In one embodiment, the fixing member is a screw.

The handle assembly 30 includes a handle 31, a rotating shaft 32, a torsion spring 33, and a snap hook 34. The handle 31 is hinge mounted on the second connecting plate 112 through the rotating shaft 32 on one end of the second connecting plate 112, and the handle 31 can be accommodated in the second connecting plate 112 by rotation, so as to facilitate the installation and removal of the tray body 10. The handle 31 includes a first connecting portion 311 and a second connecting portion 312. The first connecting portion 311 and the second connecting portion 312 are located at one end of the handle 31. The first connecting portion 311 and the second connecting portion 312 are arranged symmetrically. The first connecting portion 311 defines a second through hole 3111, and the second connecting portion 312 defines a third through hole 3121. The second through hole 3111 and the third through hole 3121 receive the rotating shaft 32. In one embodiment, the first connecting portion 311 is substantially circular, and the second connecting portion 312 is substantially cam-shaped. The handle 31 further defines a second slot 313, and the snap hook 34 is received in the second slot 313. The torsion spring 33 is sleeved on the rotating shaft 32, such that one end of the torsion spring 33 passes through one end of the handle 31, and another end of the torsion spring 33 is accommodated on the second connecting plate 112 to restrict rotation of the handle 31. The snap hook 34 is located at one end of the handle 31. The snap hook 34 includes a latching portion 341 and a locking portion 342. The locking portion 342 protrudes from the latching portion 341 and engages with the fixing groove 1122. The latching portion 341 includes a latching body 3411 and a resilient member 3412. The resilient member 3412 is connected to one end of the latching body 3411, and when the resilient member 3412 receives an external force, the resilient member 3412 is moved adjacent to the latching body 3411 to be installed to the second slot 313. In use, the handle assembly 30 presses the resilient member 3412 to push the snap hook 34 into the second slot 313 at one end of the handle 31. When the handle 31 rotates, the locking portion 342 is engaged in the fixing groove 1122, so that the handle 31 and the second connecting plate 112 are tightly connected. In one embodiment, the snap hook 34 is made of plastic.

The tray device 100 further includes an insulating sheet 41 and a resilient sheet 51. The insulating sheet 41 is mounted on the bracket 20. The insulating sheet 41 directly contacts the hardware to be installed to achieve insulation and ensure safety.

The resilient sheet 51 is connected to a side of the second connecting plate 112. In one embodiment, the resilient sheet 51 is an electromagnetic interference (EMI) sheet. The resilient sheet 51 is in close contact with the hardware to be placed and the tray body 10 to effectively reduce radiation. The resilient sheet 51 defines a plurality of holes (not labeled). The resilient sheet 51 is further provided with a plurality of hooks 511 for snapping on an edge of the snap groove 1121 to achieve a fixed connection between the resilient sheet 51 and the second connecting plate 112. In one embodiment, the number of the hooks 511 is six, and two groups of three hooks 511 are arranged symmetrically.

In one embodiment, an electronic device housing includes a cabinet and the tray device 100, and the tray device 100 is connected to the cabinet for receiving a hard disk.

When a 2.5-inch hard disk is installed on the tray device 100, the 2.5-inch hard disk is fixed to the bracket 20 by screws. The screws can be loosened to disassemble the 2.5-inch hard disk.

When a 3.5-inch hard disk is installed on the tray device 100, the 3.5-inch hard disk is placed on the bracket 20 at a certain angle for installation. To disassemble the 3.5-inch hard disk, the protrusions 1111 are pressed.

When the tray device 100 is used in a server, the tray device 100 is fixed to a server case through the handle 31 engaging with a hole of the server case during installation, and it is only necessary to rotate the handle 31 for disassembly so that the second connecting portion 312 leaves a corresponding hole of the server case.

The above-mentioned tray device 100 has a low cost, tool-free assembly and disassembly, and high versatility for carrying various types of hard disks.
